Thank you for your inquiry. It’s currently under review and analysis. I’ll get back to you as soon as there are any helpful findings or insights.
And if I understand correctly, your end goal is to access the Raspberry Pi / SSH (or web server) remotely from the WAN, and you already have a static public IP assigned, correct?
In that case, the port forwarding rule should point to the source zone “WAN” rather than “LAN”.
Thank you for your patience while we review this further.
